[0047] The paralleling device 4 is connected to the generators 2 respectively, and outputs multiple generators 2 in parallel.

[0048] A controller 3, which is respectively connected to a plurality of the gas / fuel engines 1, performs power distribution according to the output power of the energy-saving generating sets, determines the fuel supply / gas supply of each of the gas / fuel engines 1, and then sends Control instruction;

[0049] The gas / oil engine 1 adjusts its own oil supply / gas supply after receiving the control command from the controller 3 .

[0050] In this w...

Embodiment 2

[0053] As the above-mentioned energy-saving generating set, the difference of this embodiment is that, as figure 2 As shown, the controller 3 includes:

[0054] A power acquisition unit 31, which acquires the total output power to be provided by the generating set;

[0055] A list obtaining unit 32, which obtains a list of relationships between the output power of each generator and the fuel consumption / gas consumption;

[0056] A power calculation unit 33, which is connected to the power acquisition unit 31 and the list acquisition unit 32, and calculates the output power that each generator needs to provide;

[0057] The power conversion unit 34 is connected with the list acquisition unit 32 and the power calculation unit 33, and after receiving the output power of each generator sent by the power calculation unit 33, queries the corresponding fuel consumption / consumption Gas volume and converted to corresponding oil supply volume / air supply volume;

[0058] The control ...

Embodiment 3

[0061] The difference between this embodiment and the above-mentioned energy-saving generator set is that the calculation formula for calculating the output power of each generator by the power calculation unit 33 is:

[0062]

[0063] In the formula, p ia Determined by:

[0064]

[0065]

[0066] Among them, i is the serial number of the generator, j is the serial number of the power point of each generator, p ij is the output power corresponding to the jth power point of the i-th generator, h ij is the fuel consumption / air consumption corresponding to the jth power point of the i-th generator, k ij is the power consumption ratio corresponding to the jth power point of the i-th generator, k im is the maximum power consumption ratio of the i-th generator, p im is the output power corresponding to the maximum power consumption ratio of the i-th generator, n is the total number of generators that need to participate in power generation, p n is the output power of t...

Abstract

The invention discloses an energy-saving power generation unit which comprises gas / oil engines, power generators, a paralleling device and a controller. The gas / oil engines convert chemical energy of gas / oil into mechanical energy, the power generators are connected with the gas / oil engines to convert the mechanical energy into electric energy, the paralleling device is respectively connected with the power generators to parallel the same for outputting, the controller is respectively connected with the gas / oil engines, allocates power according to output power of the energy-saving power generation unit, determines oil supply / oil gas of the gas / oil engines and then sends a control instruction, and the gas / oil engines after receiving the control instruction from the controller adjust own oil supply / gas supply. In this way, the output power is reasonably allocated through the controller, so that energy sources consumed by the whole power generation unit are saved.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to an energy-saving generator set. Background technique [0002] Energy conservation is one of the issues that need to be solved urgently in the society, especially in the field of power generation. [0003] Existing generator sets of diesel generators, gasoline generators, and gas generators are all running on a single machine or in parallel. To meet its needs, two or more generators are generally required to form a generator set; but for a generator set, its fuel / gas consumption rate (fuel / gas consumed per unit of power generation) will increase as the load decreases during operation. In addition, for a generator set composed of two or more generators, the power of each engine is distributed, because the generators that make up the generator set have the same operation due to their model or individual differences. The fuel / gas consumption rate (fuel / gas consumed per unit of p...
